Speaking to Eurosport, the Swedish superstar said: "My relationship with Paul is really easy, I talk, he listens.

"All the jealous people talking about him will swallow all of the words they have said about him.

"He will only improve and will get everyone behind him."

Meanwhile United have reportedly written to fans ahead of their Europa League clash with Feyenoord.

According to the Daily Mail, supporters travelling to Holland for the tie have been told to “dress conservatively”, which could be a warning not to wear club colours.

The club have also asked fans to keep a low profile and stay away from areas of potential conflict.

Only 1,400 supporters will be making the trip to Rotterdam after Feyenoord halved their stadium capacity in order to try and avoid further sanctions following clashes during their Europa League last 32 tie with Roma in February.
